Hereinafter, embodiments relating to one aspect of the present invention will be described with reference to the drawings.
§1. Application Example FIG. 1 is a diagram showing an installation example of the composite sensor unit 1 in the present embodiment. In the present embodiment, a plurality of composite sensor units 1 are provided in the user's home as a measurement target, and the plurality of composite sensor units 1 constitute the sensor system 10. Further, the sensor system 10 may include a user terminal 2 and a gateway 3. The composite sensor unit 1 transmits the detected data to the user terminal 2 and the gateway 3. For example, when the user terminal 2 exists in the user's home, the user terminal 2 directly receives data from the composite sensor unit 1 by short-range wireless communication. When the user terminal 2 exists outside the user's home, the gateway 3 receives data from the composite sensor unit 1, transmits this data to the application server 4 via a network N such as the Internet, and the application server 4 receives data from the composite sensor unit 1. The received data is processed, and the processing result is transmitted to the user terminal 2 via the network N. The application server 4 is not an essential configuration, and the gateway 3 may connect to the user terminal 2 via the network N and transmit the data received from the composite sensor unit 1 to the user terminal 2. In this embodiment, the composite sensor unit 1 is a form of a sensor device.

FIG. 2 is a block diagram showing the configuration of the composite sensor unit 1. The composite sensor unit 1 includes a plurality of sensors 1A to 1Q, a data acquisition unit 12, an event determination unit 13, an operation setting unit 14, a memory 15, and a communication control unit 16 in one package.

The plurality of sensors 1A to 1Q are sensors that measure different types of physical quantities for each measurement target and obtain measurement data, and the data acquisition unit 12 acquires measurement data from each of the sensors 1A to 1Q.

The event determination unit 13 determines that the predetermined event has occurred when the output values of at least a part of the plurality of sensors 1A to 1Q satisfy the event conditions corresponding to the occurrence of the predetermined event. do. Further, in the event determination unit 13, the output value of the sensor including the sensor necessary for determining the occurrence of the related event, which is an event that can occur in connection with the occurrence of the predetermined event, among the plurality of sensors 1A to 1Q, is determined. It is determined that the related event has occurred when the related event condition corresponding to the occurrence of the related event is satisfied.

The operation setting unit 14 sets the plurality of sensor 1A to 1Q operations according to the presence or absence of an event. For example, when an event occurs, the measurement frequency by each sensor 1A to 1Q is set higher than when the event does not occur.

The communication control unit 16 is an example of a transmission control unit that transmits data to other devices such as a user terminal 2, a gateway 3, and another composite sensor unit 1. As will be described later, the composite sensor unit 1 includes a communication module that performs wireless communication in accordance with a wireless communication standard such as Bluetooth (registered trademark), and the communication control unit 16 communicates with another device using this communication module. For example, the communication control unit 16 stores the transmission data in which the measurement data by the sensors 1A to 1Q is in a predetermined data format in the Bluetooth advertisement packet and transmits the transmission data. The communication control unit 16 may store the transmission data in the scan response packet for the scan request and transmit the data. Hereinafter, only the advertisement packet will be described, but the advertisement packet in the following description may be replaced with the scan response packet to transmit transmission data. Further, the communication control unit 16 makes the data format of the transmission data different depending on whether the event has not occurred or the event has occurred. FIG. 3 is a diagram showing a data format of transmission data transmitted by the communication control unit 16. In the present embodiment, the data format of the transmission data defines, for example, the type of data included in the transmission data and the transmission timing. In FIG. 3, time is taken on the horizontal axis, a thick solid line orthogonal to the horizontal axis indicates the measurement timing, and a shaded rectangle indicates the transmission timing of the transmission data. The difference in the transmitted data to be transmitted, that is, the difference in the data format is shown by the difference in the shading of each rectangle.

As shown in FIG. 3, when no event has occurred, the communication control unit 16 transmits the transmission data in the first format F1. Here, the first format F1 includes temperature, humidity, and illuminance. Then, when the event determination unit 13 determines that an event such as an earthquake has occurred based on the measurement data by the sensors 1A to 1Q, the communication control unit 16 alternately transmits the first format and the second format F2. Here, the second format F2 includes the SI value and the seismic intensity.

As described above, in the present embodiment, the composite sensor unit 1 stores the transmission data in the Bluetooth advertisement packet and transmits the data, so that the user terminal 2 does not have to connect to the plurality of composite sensor units 1, respectively. Transmission data can be received from the composite sensor unit 1. In this case, the amount of measurement data that can be transmitted is limited by using the advertisement packet, but in the present embodiment, the data format of the transmission data is changed when an event occurs, and the data format according to the event is changed. You can send the transmission data with. Therefore, for example, when an earthquake occurs, transmission data including the SI value and the seismic intensity can be transmitted, and appropriate transmission data according to the event can be transmitted. As a result, the user can acquire the information necessary when the event occurs.

When the event occurrence time (schedule) is set as the event value, it is determined that the event has occurred at that time regardless of the output values of the sensors 1A to 1Q.

The target period is a period in which the output values of the sensors 1A to 1Q are acquired in order to determine the occurrence of an event such as a predetermined cycle or a predetermined time, that is, a period in which the measurement by the sensors 1A to 1Q is performed.

The target sensor is a sensor 1A to 1Q that uses an output value to determine the occurrence of an event, that is, a sensor required to determine the occurrence of an event. The target sensor can be set as a single sensor or a plurality of sensors. In addition, when multiple sensors are used as target sensors, it is judged that an event has occurred when the output values of all the target sensors correspond to the event values, or the output values of any of the target sensors correspond to the event values. In some cases, it may be specified whether the event is determined to have occurred. Further, the communication control unit 16 may be one of the sensors, the communication control unit 16 may be designated as the target sensor, and the communication quality and the number of communications may be used as the event value.

The weight is a coefficient that specifies the priority of a plurality of event conditions. For example, the larger the weight coefficient, the higher the priority of the event.

FIG. 6 is a diagram showing a hardware configuration of a computer (information processing device) such as a composite sensor unit 1, a user terminal 2, a gateway 3, and an application server 4.

The CPU 111 is not limited to a single processor, and may have a multiprocessor configuration. Further, a single CPU connected by a single socket may have a multi-core configuration. Even if at least a part of the processing of each of the above parts is performed by a processor other than the CPU, for example, a dedicated processor such as a Digital Signal Processor (DSP), a Graphics Processing Unit (GPU), a numerical arithmetic processor, a vector processor, or an image processing processor. good.

FIG. 7 is a diagram showing a flow of processing in which the composite sensor unit 1 performs measurement by each of the sensors 1A to 1Q and transmits the measurement result. The composite sensor unit 1 starts the process of FIG. 7 when the power is turned on or when the start of measurement is instructed. First, the composite sensor unit 1 determines whether or not the measurement timing has been reached (step S10). This measurement timing is set in advance so as to measure at a predetermined time interval, for example, every second. In the example of FIG. 7, only one determination process for determining whether or not the measurement timing has been reached is shown, but each sensor 1A to 1Q may be measured at different timings.

If the determination is affirmative in step S10, the sensors 1A to 1Q perform the measurement, and the data acquisition unit 12 acquires the measurement data from the sensors 1A to 1Q (step S20). If a negative determination is made in step S10, the composite sensor unit 1 shifts to step S30 without executing step S20.

In step S30, the composite sensor unit 1 determines whether or not an event has occurred. If the negative determination is made in step S30, the composite sensor unit 1 determines whether or not the transmission timing has been reached next (step S40). Here, the transmission timing is set in advance so as to transmit at a predetermined time interval, for example, every 318.75 ms. In the present embodiment, the transmission data is stored in the advertisement packet of BLE and transmitted at predetermined intervals.

In the case of a negative determination in step S40, the composite sensor unit 1 ends the process of FIG. 7, and in the case of an affirmative determination, the composite sensor unit 1 transmits transmission data in the first format F1 (step S50). As shown in FIG. 3, the transmission data in the first format has a configuration including a measurement No., a format No., a temperature, a humidity, and an illuminance. The measurement No. is, for example, identification information such as a serial number that specifies the measurement timing. The format No. is, for example, identification information that identifies the format of the transmitted data. If the format No. is "1", it indicates that it is the first format F1. Further, the first format F1 has a configuration including temperature, humidity, and illuminance as types of measurement data.

On the other hand, if the determination is affirmative in step S30, the composite sensor unit 1 determines whether or not the transmission timing has been reached as in step S40 (step S60). Since the composite sensor unit 1 of the present embodiment alternately transmits the first format F1 and the second format F2 when an event occurs, a predetermined time is required after the transmission of the second format F2. When the elapse has passed, it is determined that the transmission timing of the first format F1 has been reached. If a positive determination is made in step S60, the composite sensor unit 1 transmits transmission data in the first format F1 (step S70). If a negative determination is made in step S60, the composite sensor unit 1 shifts to step S80 without executing step S70.

Then, the composite sensor unit 1 determines whether or not the transmission timing has been reached in the same manner as in step S40 (step S80). The composite sensor unit 1 of the present embodiment determines that the transmission timing of the second format F2 has been reached when a predetermined time has elapsed after the transmission of the first format F1. In the case of a negative determination in step S80, the composite sensor unit 1 ends the process of FIG. 7, and in the case of an affirmative determination, the composite sensor unit 1 transmits transmission data in the second format F2 (step S90). The composite sensor unit 1 repeatedly executes the process of FIG. 7 until the power is turned off or the measurement is instructed to stop.

As shown in FIG. 3, the transmission data in the second format has a format number of "2" and includes a SI value and a seismic intensity as the type of measurement data. FIG. 8 is a diagram showing a frame format of the advertising packet. The communication control unit 16 of the composite sensor unit 1 stores the transmission data in the first format F1 or the second format F2 in steps S50, S70, and S90 in the payload unit of the PDU in the advertisement packet shown in FIG. .. For example, the transmission data is stored in the payload part of the advertisement packet and transmitted. As a result, the user terminal 2 that has received the advertisement packet can recognize what kind of measurement data is stored by referring to the format No. of the payload unit. As a result, for example, if the format No. is "1", the measurement data in the advertisement packet is acquired as data of temperature, humidity, and illuminance, and if the format No. is "2", the measurement data in the advertisement packet is SI. It can be acquired as value and seismic intensity data.

In the present embodiment, an example of sending transmission data in the second format when an event occurs is shown, but the format of the transmission data to be transmitted after the event may be determined according to the event. For example, when an earthquake occurs as an event, the second format F2, when a fire occurs, the nth format Fn, when a power failure occurs, the mth format Fm, etc. The relationship may be stored in a memory, and the communication control unit 16 may transmit transmission data in a format corresponding to the event that has occurred based on this correspondence.

As described above, in the present embodiment, when the event does not occur, the transmission data is transmitted in the first format F1, and when the event occurs, the transmission data in the first format F1 and the second format The transmission data in the format F2 of the above is transmitted alternately. For example, in the present embodiment, when an event occurs, the time slot every 318.75 ms is time-divisioned, and the transmission data in the first format F1 and the transmission data in the second format F2 are alternately transmitted. ing.

As described above, according to the present embodiment, when an event occurs, the format of the transmission data can be changed and appropriate measurement data corresponding to the event can be transmitted. Therefore, it is possible to transmit without reducing the amount of information such as omitting some data.

Further, in the present embodiment, since the transmission data is periodically transmitted, if the user terminal 2 or the gateway 3 cannot receive the transmission data at a predetermined timing, it is detected that an abnormality has occurred in the composite sensor unit. can.

(2-2)
Hereinafter, embodiments in which the transmission frequency of a specific format is changed after the occurrence of an event will be described with reference to FIGS. 9 to 10. The same elements as those in the above-mentioned application examples and the embodiment (2-1) are designated by the same reference numerals, and the description thereof will be omitted again.

FIG. 9 is a diagram showing a data format of transmission data in the embodiment (2-2), and FIG. 10 is a diagram in which the composite sensor unit 1 of the embodiment (2-2) measures by each sensor 1A to 1Q. It is a figure which shows the flow of the process of transmitting a result.

When the composite sensor unit 1 starts the process of FIG. 10, it first determines whether or not the measurement timing has been reached (step S100). This measurement timing is set in advance so as to measure at a predetermined time interval, for example, every second. In the example of FIG. 10, only one determination process for determining whether or not the measurement timing has been reached is shown, but each sensor 1A to 1Q may be measured at different timings.

If the determination is affirmative in step S100, each sensor 1A to 1Q performs measurement, and the data acquisition unit 12 acquires measurement data from each sensor 1A to 1Q (step S105). If the negative determination is made in step S100, the composite sensor unit 1 shifts to step S110 without executing step S105.

In step S110, the composite sensor unit 1 determines whether or not an event has occurred. If the negative determination is made in step S110, the composite sensor unit 1 sets the frequency of transmission data in a specific format to a low frequency (step S120). In the present embodiment, the frequency of transmission data in the second format is set lower than when an event occurs. For example, as shown in FIG. 9, the transmission frequency of the transmission data in the first format and the transmission frequency of the transmission data in the second format are set to 1: 1.

Then, the composite sensor unit 1 determines whether or not the transmission timing of the transmission data in the second format has been reached based on the frequency set in step S120 (step S130). If the determination is affirmative in step S130, the composite sensor unit 1 transmits the transmission data in the second format (step S140), and if the determination is negative in step S130, the composite sensor unit 1 is in the first format. (Step S150). The composite sensor unit 1 repeatedly executes the process of FIG. 10 until the power is turned off or the measurement is instructed to stop. Therefore, when no event has occurred, the composite sensor unit 1 alternately performs affirmative determination and negative determination in step S130, and transmits data in the first format and transmission data in the second format. And are transmitted alternately.

On the other hand, when an event occurs and an affirmative determination is made in step 110, the composite sensor unit 1 sets the frequency of transmission data in a specific format to a high frequency (step S160). In the present embodiment, the frequency of transmission data in the second format is set higher than when an event occurs. For example, as shown in FIG. 9, the transmission frequency of the transmission data in the first format and the transmission frequency of the transmission data in the second format are set to 1: 2.

Then, the composite sensor unit 1 determines whether or not the transmission timing of the transmission data in the second format has been reached based on the frequency set in step S160 (step S170). If the determination is affirmative in step S170, the composite sensor unit 1 transmits the transmission data in the second format (step S180), and if the determination is negative in step S170, the composite sensor unit 1 is in the first format. (Step S190). When an event occurs in this way, the composite sensor unit 1 performs a negative determination and an affirmative determination 1: 2 in step S170, and transmits data in the first format and transmission data in the second format. And are transmitted at a frequency of 1: 2.

As described above, in the present embodiment, when an event occurs, the transmission frequency of the transmission data in the second format F2 is higher than in the case where the event does not occur. As a result, when an event occurs, more measurement data corresponding to the event that has occurred can be acquired. In the present embodiment, after the event occurs, the frequency of transmission of the measurement data in the second format is increased to reduce the frequency of transmission of the measurement data in the first format. It is not limited. For example, after the event occurs, the transmission frequency of the advertisement packet is increased as compared with the case where the event does not occur, that is, the transmission interval is shortened, so that the transmission frequency of the measurement data in the first format is not reduced. , The frequency of transmission of the measurement data in the second format may be increased.

(2-3)
Hereinafter, an embodiment in which transmission data in a format including the increased measurement data is transmitted after increasing the number of measurements of the measurement data after the occurrence of the event will be described with reference to FIGS. 11 to 12. The same elements as those in the above-mentioned application examples and embodiments are designated by the same reference numerals, and the description thereof will be omitted again.

FIG. 11 is a diagram showing a data format of transmission data in the embodiment (2-3), and FIG. 12 is a diagram in which the composite sensor unit 1 of the embodiment (2-3) measures by each sensor 1A to 1Q. It is a figure which shows the flow of the process of transmitting a result.

When the composite sensor unit 1 starts the process of FIG. 12, it first determines whether or not an event has occurred (step S200). If a negative determination is made in step S200, the composite sensor unit 1 sets the measurement interval by each sensor 1A to 1Q as a standard interval, and sets the measurement frequency to be lower than when an event occurs (step S205). .. Next, the composite sensor unit 1 determines whether or not the measurement timing has been reached based on the measurement frequency set in step S205 (step S210). This measurement timing is set in advance so as to measure at a predetermined time interval, for example, every second. In the example of FIG. 12, only one process for determining whether or not the measurement timing has been reached is shown, but each sensor 1A to 1Q may be measured at different timings.

If the determination is affirmative in step S210, the sensors 1A to 1Q perform the measurement, and the data acquisition unit 12 acquires the measurement data from the sensors 1A to 1Q (step S215). If the negative determination is made in step S210, the composite sensor unit 1 shifts to step S220 without executing step S215.

In step S220, the composite sensor unit 1 determines whether or not the transmission timing of the transmission data has been reached. In the case of a negative determination in step S220, the composite sensor unit 1 ends the process of FIG. 12, and in the case of an affirmative determination, the composite sensor unit 1 transmits transmission data in the first format F1 (step S225).

On the other hand, if the determination is affirmative in step S200, the composite sensor unit 1 is set so that the measurement interval between the sensors 1A to 1Q is shorter than the standard and the measurement frequency is higher than when no event occurs. (Step S235). Next, the composite sensor unit 1 determines whether or not the measurement timing has been reached based on the measurement frequency set in step S235 (
Step S240). This measurement timing is set in advance so as to measure at predetermined time intervals, for example, every 250 ms.

If the determination is affirmative in step S240, each sensor 1A to 1Q makes a measurement, and the data acquisition unit 12 acquires measurement data from each sensor 1A to 1Q (step S245). If a negative determination is made in step S240, the composite sensor unit 1 shifts to step S250 without executing step S245.

In step S250, the composite sensor unit 1 determines whether or not the transmission timing of the transmission data in the first format has been reached. If the determination is affirmative in step S250, the composite sensor unit 1 transmits the transmission data in the first format (step S2).
55) If a negative determination is made in step S250, the composite sensor unit 1 transmits transmission data in the third data format F3 (step S260). Here, as shown in FIG. 11, the transmission data in the third data format F3 includes the measurement No., the format No., and the temperature data measured at a plurality of measurement timings. In the example of FIG. 11, the third data format F3 is configured to include temperature data for four times measured at intervals of 250 ms.

As described above, in the present embodiment, when an event occurs, the measurement frequency by the sensor is increased as compared with the case where the event does not occur, and the third data including the measurement data measured at a plurality of measurement timings. The transmission data in format F3 is transmitted. As a result, when an event occurs, more measurement data corresponding to the event that has occurred can be acquired.

(2-4)
Hereinafter, an embodiment in which data including data indicating a failure is transmitted when a failure occurs in the composite sensor unit 1 will be described with reference to FIGS. 13 to 14. The same elements as those in the above-mentioned application examples and embodiments are designated by the same reference numerals, and the description thereof will be omitted again.

When the composite sensor unit 1 starts the process of FIG. 14, it first determines whether or not the measurement timing has been reached (step S310). This measurement timing is set in advance so as to measure at a predetermined time interval, for example, every second. In the example of FIG. 14, only one process for determining whether or not the measurement timing has been reached is shown, but each sensor 1A to 1Q may be measured at different timings.

If the determination is affirmative in step S310, the sensors 1A to 1Q perform the measurement, and the data acquisition unit 12 acquires the measurement data from the sensors 1A to 1Q (step S320). If a negative determination is made in step S310, the composite sensor unit 1 shifts to step S330 without executing step S320.

In step S330, the composite sensor unit 1 determines whether or not a failure has occurred as whether or not an event has occurred by the event determination unit 13. For example, the event determination unit 13 determines that the sensors 1A to 1Q have failed when the values of the measurement data by the sensors 1A to 1Q cannot be acquired or exceed the specified range. If the negative determination is made in step S330, the composite sensor unit 1 determines whether or not the transmission timing has been reached next (step S340).

In the case of a negative determination in step S340, the composite sensor unit 1 ends the process of FIG. 14, and in the case of an affirmative determination, the composite sensor unit 1 transmits transmission data in the first format F1 (step S350).
On the other hand, if the determination is affirmative in step S330, the composite sensor unit 1 determines whether or not the transmission timing has been reached in the same manner as in step S340 (step S360). If the affirmative determination is made in step S360, the composite sensor unit 1 transmits transmission data in the first format F1 (step S370). If a negative determination is made in step S360, the composite sensor unit 1 shifts to step S380 without executing step S370.

Then, the composite sensor unit 1 determines whether or not the transmission timing has been reached in the same manner as in step S340 (step S380). In the case of a negative determination in step S380, the composite sensor unit 1 ends the process of FIG. 14, and in the case of an affirmative determination, the composite sensor unit 1 transmits transmission data in the fourth data format F4 (step S390). The composite sensor unit 1 repeatedly executes the process shown in FIG. 14 until the power is turned off or the measurement is instructed to stop.

Here, the transmission data used as the fourth data format has a format No. "4" as shown in FIG. 13, and includes data indicating a failure of the composite sensor unit 1. As shown in FIG. 13, the communication control unit 16 sets the value of the data indicating a failure to "1" for the sensor whose measurement data is abnormal in step S330, and fails the sensor whose measurement data is not abnormal. The value of the data indicating the above is set to "0".

As described above, in the present embodiment, when a failure occurs, it is possible to indicate whether or not the composite sensor unit 1 is operating normally by transmitting data indicating the failure, and the reliability of the data can be improved. Can be secured.

(2-5)
Hereinafter, embodiments in which a plurality of types of measurement data measured by the sensor are distributed into a predetermined number of data formats and transmitted will be described with reference to FIGS. 15 to 16. The same elements as those in the above-mentioned application examples and embodiments are designated by the same reference numerals, and the description thereof will be omitted again.

When the composite sensor unit 1 starts the process of FIG. 16, it first determines whether or not the measurement timing has been reached (step S400). This measurement timing is set in advance so as to measure at a predetermined time interval, for example, every second. In the example of FIG. 16, only one determination process for determining whether or not the measurement timing has been reached is shown, but each sensor 1A to 1Q may be measured at different timings.

If the determination is affirmative in step S400, each sensor 1A to 1Q makes a measurement, and the data acquisition unit 12 acquires measurement data from each sensor 1A to 1Q (step S405). In the present embodiment, the temperature, humidity, illuminance, SI value, seismic intensity, acceleration X, acceleration Y, and acceleration Z are acquired from the sensors 1A to 1Q, and these are obtained in the first format F1 as shown in FIG. , The second format F2 and the fifth data format F5 are sorted and transmitted. Here, the fifth data format includes acceleration X, acceleration Y, and acceleration Z as measurement data.

If the negative determination is made in step S400, the composite sensor unit 1 proceeds to step S410 without executing step S405.

In step S410, the composite sensor unit 1 determines whether or not an event has occurred. If the negative determination is made in step S410, the composite sensor unit 1 next determines whether or not the transmission timing of the transmission data in the first format has been reached (step S415). For example, in the present embodiment, since the first format F1, the second format F2, and the fifth data format F5 are periodically transmitted, a predetermined time (for example, for example) after the transmission of the fifth data format F5 is performed. When 152.5 ms) has elapsed, it is determined that the transmission timing of the first format F1 has been reached.

If the determination is affirmative in step S415, the composite sensor unit 1 transmits transmission data in the first format F1 (step S420).

On the other hand, if the negative determination is made in step S415, the composite sensor unit 1 shifts to step S425 without executing step S420.

In step S425, the composite sensor unit 1 determines whether or not the transmission timing of the transmission data in the second format has been reached. For example, in the present embodiment, when a predetermined time (for example, 152.5 ms) has elapsed after the transmission of the first format F1, it is determined that the transmission timing of the transmission data in the second format F2 has been reached.

If the determination is affirmative in step S425, the composite sensor unit 1 transmits transmission data in the second format F2 (step S430).

On the other hand, if the negative determination is made in step S425, the composite sensor unit 1 shifts to step S435 without executing step S430.

In step S435, the composite sensor unit 1 determines whether or not the transmission timing of the transmission data in the fifth data format F5 has been reached. For example, in the present embodiment, when a predetermined time (for example, 152.5 ms) has elapsed after the transmission of the second format F2, it is determined that the transmission timing of the transmission data in the fifth data format F5 has been reached.

If the determination is affirmative in step S435, the composite sensor unit 1 transmits transmission data in the fifth data format F5 (step S440).

On the other hand, if a negative determination is made in step S435, the process of FIG. 16 ends. The composite sensor unit 1 repeatedly executes the process of FIG. 16 until the power is turned off or the measurement is instructed to stop.

Further, when an event occurs and a positive determination is made in step S410, the composite sensor unit 1 determines whether or not the transmission timing of the transmission data in the second format has been reached (step S445). For example, in the present embodiment, when an event occurs, the second format F2 and the fifth data format F5 are alternately transmitted, so that a predetermined time (for example, 152.5 ms) after the transmission of the fifth data format F5 is performed. When is elapsed, it is determined that the transmission timing of the transmission data in the second format F2 has been reached.

If the determination is affirmative in step S445, the composite sensor unit 1 transmits transmission data in the second format F2 (step S450).

On the other hand, if the negative determination is made in step S445, the composite sensor unit 1 shifts to step S455 without executing step S450.

Then, in step S455, the composite sensor unit 1 determines whether or not the transmission timing of the transmission data in the fifth data format F5 has been reached. For example, when a predetermined time (for example, 152.5 ms) has elapsed after the transmission of the second format F2, it is determined that the transmission timing of the transmission data in the fifth data format F5 has been reached.

If the determination is affirmative in step S455, the composite sensor unit 1 transmits transmission data in the fifth data format F5 (step S460).

On the other hand, if a negative determination is made in step S455, the process of FIG. 16 ends.

As described above, in the present embodiment, even if the measurement data acquired from each sensor 1A to 1Q cannot be stored in one advertisement packet, these measurement data are distributed to a predetermined number of data formats, and the predetermined number of data is distributed. The transmitted data in the format is transmitted periodically. This makes it possible to transmit various types of measurement data in advertisement packets. In addition, when an event occurs, the frequency of transmission of measurement data according to the event can be increased by narrowing down the types of data formats to be transmitted. As a result, it is possible to prevent the device on the receiving side from failing to receive the necessary measurement data when an event occurs.

(2-6)
Hereinafter, an embodiment in which the receiving side device receives transmission data from the plurality of composite sensor units 1 will be described with reference to FIG. The same elements as those in the above-mentioned application examples and embodiments are designated by the same reference numerals, and the description thereof will be omitted again.

FIG. 17 shows an example in which a receiving device such as a user terminal 2 or a gateway 3 receives from a plurality of (for example, four) composite sensor units 1 (1-1, 1-2, 1-3, 1-4). Is shown. Each composite sensor unit 1 (1-1, 1-2, 1-3, 1-4) measures, for example, every 250 ms, and transmits every 1000 ms in a second data format including the measurement data for these four times. Send data. In this case, each composite sensor unit 1 (1-1, 1-2, 1-3, 1-4) has a different timing of transmitting the advertising packet by 250 ms, and each composite sensor unit 1 (1) The transmission timing of the advertising packet transmitted from -1,1-2, 1-3, 1-4) may be different.

In addition, each composite sensor unit 1 (1-1, 1-2, 1-3, 1-4) stores the measurement data in the memory each time the measurement data is acquired from the sensors 1A to 1Q, and together with the receiving side device. After the connection, the transmission data may be transmitted to the connected receiving device. In this case, for example, the receiving side device (central) such as the user terminal 2 or the gateway 3 requests the connection to each composite sensor unit 1 based on the advertisement packet transmitted from each composite sensor unit (peripheral) 1. Then, a connection is established between the composite sensor unit 1 and the receiving device. In this embodiment, the communication control unit 16 of the composite sensor unit 1 is a form of a connection control device for making a connection. The receiving side device that has established the connection sequentially requests the transmission data and acquires the transmission data from the composite sensor unit 1.

As described above, according to the present embodiment, the measurement data can be transmitted from the plurality of composite sensor units 1 to the receiving side device.

(2-7)
Hereinafter, embodiments in which measurement data is transmitted with increased measurement frequency when an event occurs will be described with reference to FIGS. 18 to 22. The same elements as those in the above-mentioned application examples and embodiments are designated by the same reference numerals, and the description thereof will be omitted again. FIG. 18 is an explanatory diagram when the measurement timing and the transmission timing are changed frequently when an event occurs, and FIG. 19 is a diagram showing problems when the measurement timing and the transmission timing are changed in the plurality of composite sensor units 1. FIG. 20 is a diagram showing the measurement timing and the transmission timing in the embodiment (2-7), and FIG. 21 is a diagram in which the composite sensor unit 1 performs measurement by each sensor 1A to 1Q in the embodiment (2-7). It is a figure which shows the flow of the process of transmitting a measurement result.

In the example of FIG. 18, measurements are performed by the sensors 1A to 1Q at predetermined time intervals, and measurement data is transmitted for each measurement. In this case, when an event occurs, the measurement frequency is determined by an event. If it is higher than without it, the transmission frequency will be high as well. Therefore, as shown in FIG. 19, when the occurrence of an event is detected by the plurality of composite sensor units 1, it is conceivable that the transmission timings overlap and the transmission data cannot be received by the receiving side device. Therefore, in the present embodiment, when an event occurs and the measurement frequency is set high, the transmission data is transmitted in a data format including a plurality of times of the measurement data measured at this high frequency.

When the composite sensor unit 1 of the present embodiment starts the process of FIG. 21, it first determines whether or not an event has occurred (step S500). If a negative determination is made in step S500, the operation setting unit 14 of the composite sensor unit 1 sets the measurement interval by each sensor 1A to 1Q as a standard interval and sets the measurement frequency to be lower than when an event occurs. (Step S505).

In step S515, the composite sensor unit 1 determines whether or not the measurement timing has been reached based on the measurement frequency set in step S505. This measurement timing is set in advance so as to measure at a predetermined time interval, for example, every second. In the example of FIG. 21, only one determination process for determining whether or not the measurement timing has been reached is shown, but each sensor 1A to 1Q may be measured at different timings.

If the determination is affirmative in step S515, each sensor 1A to 1Q makes a measurement, and the data acquisition unit 12 acquires measurement data from each sensor 1A to 1Q (step S520).

Then, the composite sensor unit 1 transmits transmission data in the first format F1 (
Step S525).
If the negative determination is made in step S515, the composite sensor unit 1 ends the process of FIG. 21. The composite sensor unit 1 repeatedly executes the process shown in FIG. 21 until the power is turned off or the measurement is instructed to stop. As described above, in the present embodiment, if the negative determination is made in step S515, the process of FIG. 21 is temporarily terminated and this process is repeated again. However, the present invention is not limited to this, and sleep for a predetermined period after step S505. Then, the process proceeds to step S515, and in the case of a negative determination in step S515, the sleep may be returned and the determination in step S515 may be repeated at predetermined intervals.

On the other hand, if the determination is affirmative in step S500, the operation setting unit 14 of the composite sensor unit 1 shortens the measurement interval between the sensors 1A to 1Q from the standard, and increases the measurement frequency as compared with the case where the event occurs. (Step S535).

In step S545, the composite sensor unit 1 determines whether or not the measurement timing has been reached based on the measurement frequency set in step S535. This measurement timing is set in advance so as to measure at predetermined time intervals, for example, every 250 ms. In the example of FIG. 21, only one determination process for determining whether or not the measurement timing has been reached is shown, but each sensor 1A to 1Q may be measured at different timings.

If the determination is affirmative in step S545, each sensor 1A to 1Q makes a measurement, and the data acquisition unit 12 acquires measurement data from each sensor 1A to 1Q (step S550). If a negative determination is made in step S545, the composite sensor unit 1 ends the process of FIG. 21. The composite sensor unit 1 repeatedly executes the process shown in FIG. 21 until the power is turned off or the measurement is instructed to stop. As described above, in the present embodiment, if the negative determination is made in step S545, the process of FIG. 21 is temporarily terminated and this process is repeated again. However, the present invention is not limited to this, and sleep for a predetermined period after step S535. Then, the process proceeds to step S545, and in the case of a negative determination in step S545, the sleep may be returned and the determination in step S545 may be repeated at predetermined intervals.

Next, the composite sensor unit 1 determines whether or not the transmission timing of the transmission data in the third data format F3 has been reached (step S555). If the determination is affirmative in step S555, the composite sensor unit 1 transmits the transmission data in the third data format F3 (step S560).

As described above, in the example of FIG. 21, when an event occurs, the measurement frequency by the sensor is increased as compared with the case where the event does not occur, and the third data including the measurement data measured at a plurality of measurement timings. The transmission data in format F3 is stored in the advertisement packet and transmitted. As a result, when an event occurs, more measurement data corresponding to the event that has occurred can be acquired.

Not limited to this, when an event does not occur, the transmission data is stored in the advertisement packet and transmitted, and when an event occurs, a connection is established with the receiving device and the transmission data is sent to the data packet. It may be stored and sent. FIG. 22 is a diagram showing a processing flow when connecting to a receiving device when an event occurs.

Note that, in FIG. 22, the processes from step S500 to step S545 are the same as those in FIG. 21, and thus the description thereof will be omitted again.

In FIG. 22, when a positive determination is made in step S545, each sensor 1A to 1Q performs measurement, and the data acquisition unit 12 acquires measurement data from each sensor 1A to 1Q and stores it in a memory (step S570). On the other hand, if a negative determination is made in step S545, the composite sensor unit 1 ends the process of FIG. 22. The composite sensor unit 1 repeatedly executes the process of FIG. 22 until the power is turned off or the measurement is instructed to stop.

As described above, in the example of FIG. 22, when an event occurs, the measurement data is stored in the memory so that the transmission data can be transmitted via the connection. In this case, when an event occurs, the receiving device may be notified that the event has occurred in step S535, and the receiving device may be prompted to connect.

As described above, in the example of FIG. 22, when the event does not occur, the transmission data is stored in the advertising packet and transmitted, and when the event occurs, the connection with the receiving device is established. The transmission data is stored in the data packet, and the transmission data is transmitted via this connection (Connection). As a result, when the event has not occurred, the transmission data can be easily transmitted using the advertising packet, and when the event has occurred, the transmission data can be reliably transmitted using the data packet. By simply transmitting using the advertising packet in this way, for example, the connection processing can be omitted and the power consumption can be suppressed. In addition, when an event occurs, by using a data packet, more data can be transmitted than when an advertising packet is used, encryption and error detection become possible, and highly reliable communication can be performed. ..

Notification that an event has occurred may be given by transmitting an iBeacon®. Further, the notification indicating that an event has occurred may be, for example, transmitting an advertisement packet including a predetermined UUID. In this case, the composite sensor unit 1 includes, for example, service 0 (a service that holds data such as temperature, humidity, and illuminance), service 1 (a service that holds data such as SI value, and seismic intensity), and service 2 (high frequency). (Service that holds the temperature data measured in) shall be owned. Here, the service 1 holds data related to the earthquake, and the data is updated when an event in which an earthquake occurs occurs. Service 2 holds data that is valid in the event of a fire, and that data is updated when an event occurs in which a fire occurs.

On the other hand, the user terminal 2 and the gateway 3 store in advance the correspondence between the UUID indicating each service and the event in the memory. For example, when no event has occurred, the UUID indicating service 0 is advertised. If an earthquake occurs, the sensor detects that an event has occurred and advertises a UUID indicating service 1. The user terminal 2 and the gateway 3 confirm the received advertisement packet, determine that the UUID has changed, and know that an event related to the data of the service 1 (earthquake data service) has occurred. Therefore, after the connection, it is possible to acquire the data related to the service 1. Therefore, by transmitting the service UUID according to the event on the advertisement packet, it is possible for the user terminal 2 and the gateway 3 side to determine what kind of event occurs and what data should be acquired. Become.

Note that, for example, in the above example, when an earthquake event occurs, data can be acquired even if the service 2 (temperature data service in the event of a fire) is accessed after the connection. At that time, since no fire event has occurred, the acquired data is data that is measured (updated) less frequently than the data acquired when a fire event occurs (for example, the measurement measured in step S520). It may be (data), or it may be a Null value if there is no update after the previous acquisition.

Further, the composite sensor unit 1 stores the UUID indicating each service and the correspondence relationship with the event in the memory in advance, and changes the UUID transmitted by the advertisement packet according to the event to provide an accessible service. It may be limited. For example, in step S500 of FIG. 22, the composite sensor unit 1 transmits a UUID indicating service 0 when it is determined that an event has not occurred, and services when it is determined that an earthquake has occurred as an event. A UUID indicating 1 is transmitted. In addition, restrictions are applied so that services other than service 1 cannot be accessed inside the composite sensor unit 1. In the user terminal 2 and the gateway 3, the correspondence relationship between the UUID indicating each service and the event is stored in the memory in advance, and when the received advertisement packet includes the UUID indicating the service 1, a connection is requested. , Only service 1 can perform data communication. In this way, the user terminal 2 and the gateway 3 can recognize which data needs to be acquired.

Not only in the example of FIG. 22, but also in the embodiments (2-1) to (2-5), the transmission data is stored in the advertising packet when the event does not occur, as in FIG. 22. When transmission is performed and an event occurs, a connection with the receiving device may be established, transmission data may be stored in a data packet, and transmission data may be transmitted via this connection (Connection). For example, in the example of the embodiment (2-1), when it is determined in step S30 of FIG. 7 that an event has occurred, the UUID corresponding to the event is transmitted, instead of steps S60 to S90. , The measurement result may be stored in the memory so that it can be transmitted to the user terminal 2 or the gateway 3 via the connection. Similarly, in the example of the embodiment (2-2), when it is determined in step S110 of FIG. 10 that an event has occurred, the UUID corresponding to the event is transmitted, instead of steps S170 to S190. The measurement result may be stored in the memory. In the example of the embodiment (2-3), when it is determined in step S200 of FIG. 12 that an event has occurred, the UUID corresponding to the event is transmitted, and the measurement is performed instead of steps S250 to S260. The result may be configured to be stored in memory. In the example of the embodiment (2-4), when it is determined in step S330 of FIG. 14 that a failure has occurred, the UUID corresponding to the failure is transmitted, and the measurement is performed instead of steps S370 to S390. The result may be configured to be stored in memory. In the example of the embodiment (2-5), when it is determined in step S410 of FIG. 16 that an event has occurred, the UUID corresponding to the event is transmitted, and the measurement is performed instead of steps S445 to S460. The result may be configured to be stored in memory.
